Two new members fdt_index and fdt_index_valid are added in kimage_arch
struct to track the FDT kexec segment. These new members of kimage_arch

segment from the kexec segment array. Otherwise, we have to loop through
all kexec segments to find the FDT segments.

It seems that this is only used when CONFIG_CRASH_HOTPLUG is defined, isn't it?
Yes it should be kept under CONFIG_CRASH_HOTPLUG config.
Thanks,
